- 350 -

A simple disc is used with no linkage or close fitting
parts to eliminate problems found in ordinary small
float or piston-operated devices used in drip legs on
air lines. Disc will lift off seat on a periodic time
cycle, allowing moisture to be discharged and
atomized through the muffler. Positive action of the
disc assures reliable condensate removal with

minimum loss of air and rapid shutoff on no load condition.
Intermittent discharges atomize condensate to avoid messy
accumulations produced by other devices. Highly effective,
specially designed muffler eliminates noise and diffuses
moisture so that discharge drain piping is usually unneces­sary. Freeze proof when mounted in vertical position with
outlet facing down and muffler removed.

Condensate Removal from Air Systems

Pressures To 600 PSIG (41.4 barg)

Temperatures to 220°F (104°C)

Automatic and Positive Drain — Effectively removes

condensate from compressed air systems with minimum
air loss and rapid shutoff on no load conditions.

Reliable — Only one moving part.
Low Maintenance Cost — No adjustments necessary.

Replaceable cartridge for in line repair and/or cleaning.

Long Service Life — Stainless Steel internals.
Freezeproof — Will not freeze when installed in vertical

position with muffler removed.

Quiet Operation — Meets OSHA noise standards.
Simplifies Startup — No need to drain air lines through

manual valves or petcocks. Top performance is reached
without waiting for system to purge.

Sized for Most Applications — Drain-Air available in 3/8"

and 1/2"; Mini-Drain available in 1/8" and 3/8".
